Case Type   : 事件触发器
Case Name   : 【事件触发器】ALTER DEFAULT SEQUENCE命令触发事件触发器
Create At   :2024/07/08
Owner       :sungang14
Description :
    预置条件：
        1.创建事件触发器：
        CREATE OR REPLACE FUNCTION f_eventtrigger_00056()
        RETURNS event_trigger
        LANGUAGE plpgsql
        AS $$ BEGIN
        RAISE NOTICE 'test_event_trigger: % %', tg_event, tg_tag;
        END;
        $$;
        CREATE EVENT TRIGGER start_eventtri ON ddl_command_start EXECUTE PROCEDURE f_eventtrigger_00056();
        CREATE EVENT TRIGGER end_eventtri ON ddl_command_end EXECUTE PROCEDURE f_eventtrigger_00056();
        CREATE EVENT TRIGGER drop_eventtri ON sql_drop EXECUTE PROCEDURE f_eventtrigger_00056();
        CREATE EVENT TRIGGER rewrite_eventtri ON  table_rewrite EXECUTE PROCEDURE f_eventtrigger_00056();
    测试步骤：
        1、CREATE SEQUENCE seq_test;
        3、ALTER SEQUENCE seq_test MAXVALUE 999;
        2、DROP SEQUENCE seq_test;
Expect      : 
    1、触发执行函数f_eventtrigger_0005()
        test_event_trigger: ddl_command_start,CREATE SEQUENCE
        test_event_trigger: ddl_command_end,CREATE SEQUENCE
    2、触发执行函数f_eventtrigger_0005()
        test_event_trigger: ddl_command_start,ALTER SEQUENCE
        test_event_trigger: ddl_command_end,ALTER SEQUENCE
    3、触发执行函数f_eventtrigger_0005()
        test_event_trigger: ddl_command_start,DROP SEQUENCE
        test_event_trigger: sql_drop,DROP SEQUENCE
        test_event_trigger: ddl_command_end,DROP SEQUENCE
